.SS nonceVerifierLength
The \fInonceVerifierLength\fR parameter is the length of the nonceVerifier.
.SS nonceVerifier
The \fInonceVerifier\fR parameter is the challenge for the platform.
.SS baseNameLength
The \fIbaseNameLength\fR parameter is the length of the baseName.
.SS baseName
The \fIbaseName\fR parameter is the base name that was chosen for the DAA Signature.

.SH "RETURN CODES"
.PP
\fBTspi_DAA_VerifyInit\fR returns TSS_SUCCESS on success, otherwise one of the
following values is returned:
.TP
.SM TSS_E_BAD_PARAMETER
.TP
.SM TSS_E_INTERNAL_ERROR
